Ultra-Efficient Engines and Fuels

The Ultra-Efficient Engines and Fuels program is collaborative project, funded by the UK's Engineering and Physical Sciences Research Council (EPSRC) that aims to provide a step-change in engine efficiency through the co-development of novel combustion systems and matched fuels from sustainable sources.

The Oxford group's contribution to the program is focussed on delivering fundamental scientific data on fuel spray behaviour and the auto-ignition characteristics of new fuels under the extreme in-cylinder conditions that characterise many of the novel combustion concepts being developed by our project partners.

 Cold Driven Shock Tube (CDST)

A key element of our program, and a potentially significant legacy of the Ultra funding, has been the development of new facilities and optical diagnostic techniques. We will shortly (June 2017) be commissioning a dedicated cold-driven shock tube capable of proving controlled pressures and temperatures up to 150 bar and 1500 K for fuel spray and auto-ignition studies. We have, in a world first, built a portable system for Laser Induced Thermal Grating Spectroscopy (LITGS), and have applied this system to measure in-situ gas temperatures in a collaborator's test facility. We have also demonstrated, in another world first, high-speed LITGS, showing the measurement techniques potential for high-presicion temperature measurements in transient phenomena. A commercialisation agreement for the portable LITGS system has been signed with a leading supplier of laser diagnostic equipment.
